To all whom z'if nztay concern:

Be it known. that I, LIONEL L. Farmer, a subject oftheKing of Great Britain, residing at Fort lVilliam, in the Provinceof Ontario, Dominion of Canada, have invented new and useful Improvements in Folding and Adjustable Childrens Seats, 'of which the following is a specification.

The invention to relates to a folding and adjustable childs seat.

In order to more clearly disclose the con- 'struction, operation, and use of the invention reference should be had to the accompanying drawings forming part of the present application. Throughout the several figures of the drawings like reference characters designate the same parts.

In the drawings Figure l is a front view of the invention applied;

.Fig. 2 is a side elevation of the same;

Fig. 3 is a top plan View of the same; Fig. 4 is an enlarged front view of the seat folded; and

Fig. 5 is a top plan view of Fig. 4.

The main objects of the invention are to produce a simple, efficient, compact, economical, and durable, childs seat which may be easily and quickly collapsed or folded into minimum space and readily adjusted as desired, and also a seat which may be attached and detached as quickly and conveniently as possible.

Referring to the drawings in detail, 1 indicates the seat base. ear each end of the base is pivotally mounted an arm formed of heavy wire bent into the form of a broad U with a front vertical branch2, a rear ver tical branch 3, and a connecting branch 4. At the angle formed by branches 2 and t, the wire is coiled to form a loop or eye 5 for a purpose to be later disclosed. The free end of each vertical arm is slightly ofi-set inwardly, flattened, and perforated as at G for the passage of a small attaching screw, nail, or the like 7. These screws or nails are not driven in tight enough to bind the part 6 against the edge of the base 1. They are left just sufliciently loose to allow the branches 2 and 3 to swing around them as on pivots or pintles, and the off set at the free end of each of these branches spaces them from the edge of the base so that they may be folded down close and compactly on the base 1, as in Figs. 4 and 5, The heads single arm at each end of be hereinafter described of the screws or nails, of course, prevent the branches 2 and 3 from slipping off their pivots. Properly speaking, the branches 2, 3, and 4, may be considered together as a the base 1, and. will be soreferred to in some of the claims.

The seat, as a whole, is designed to be used as a simple attachment for the ordinary chair to take the place of a high-chair. It is adapted to be suspended from the top rail or a cross rail of the chair back as shown in Figs. 1, 2, and 3. To that end two suspension hooks are provided. From each hook extends a rod 9 the lower part of-which is formed as a resilient, extensible coil 10. The inside diameters of. the spirals of each coil, when not eXtended, are substantially the same as the diameterof the branches 3. These coils are disposed about the branches 3. N ow, when the coil is extended each spiral is contracted to a certain extent and its diameter decreased. This causes a, tight binding action between the coil and branch 3, resulting in a solid, friction grip. Or, in the lowest position of the seat, indicated in dotted lines in Fig. 2, the coils are not extended and the seat is held simply by ongagement of the upper spiral with the branch 4:. If it should be desired to hold the seat somewhat higher than shown, it would only be necessary to lift it so that the strain would be taken off the coils and slide the branches up through the coils until the lower spiral reaches the base 1, for instance, and then extend the upper spirals of the coils by holding the lower spirals while pulling down on the base 1. The upper spirals will then get a frictional hold, as previously explained. In this way, the seat may be held at various heights which is a great advantage.

The pivotal connection of the arms and the attached suspending sible to attach the seat either to a curved back or a straight back chair, as will be readily understood.

he eyes 5 are intended to receive either a strap or the like to prevent a child from tumbling out; or the pintles of the usual swinging shelf common with high chairs. Such devices are well known and therefore it is not thought necessary to illustrate them in connection with the present invention.

Preferably, the hooks are covered with rubber tubing or the like 11, to prevent damage to the chair back, strip of felt on hooks makes it posother bufling material 12 is secured to the rear edge of the base 1 for the same purpose.

It is thought that the construction, operation, and use of the invention will be clear from the preceding detailed description.

Changes may be made in the construction, arrangement, and disposition of the several parts of the invention, Within the scope of the appended claims, Without in any Way departing'from'the field and scope of'the invention, and it is meant to include all such Within this application wherein only a preferred form has been shown by Way of illustration.

Having described my invention, What I claim and desire to protect by Letters Patent of the United States is 1. A childs seat of the character described comprising, a base, arms pivotally secured thereto, extensible coils disposed about said arms and adapted to frictionally grip the same to sustain the Weight of the seat, and

hooks carried by said coils.

2. A childs seat of the character described comprising, a base, arms secured to the oppo-' site ends thereof and each provided With a' vertical branch,

a spring coil disposed about each vertical branch and adapted to frictionally engage the same Copies of this patent may be obtained for to suspend the seat,

five cents each, by addressing the Washington, D. 6.

coils being also adapted to engage the other branch of each arm when the seat is in its lowermost position, and suspension hooks carried by sald spring co1ls.

41., A childs seat of the characterdescribed comprising, a base, U shaped arms pivotally secured to the opposite ends of said, base and each consistingof tWo vertical branches connected by a horizontal branclnand rods provided With suspension'hooks at their upper ends disposed about one of the aforesaid vertical and each formed with a spring coil branches and adapted to frictionally engage the same to suspend the seat at various heights, and also adapted toengage the horizontal branch of the arm to suspend the seat in its lowermost position.
